mount USB flash problem

[trinitry]

hi all, i am new also in ubuntu, i an using kubuntu and i have a problem when i am trying to mount manually the usb flash stick i have (automatically doesnt the system respond when i am pluging it). as i see in other threads the output of the command dmesg |grep usb shows:

[17179581.688000] usbcore: registered new driver usbfs
[17179581.688000] usbcore: registered new driver hub

[17186136.300000] usb-storage: waiting for device to settle before scanning
[17186141.388000] usb-storage: device scan complete

and when i give : sudo mount /dev/sdb -t vfat /mnt/flash
i get :
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

i try also: sudo mount -t autofs /mnt/flash and i got the same,,,,
what i should do couse important things are in that stick help!!!!

Re: mount USB flash problem

Try to mount sdb1.

BTW, for usb sticks is usually better to use: pmont /dev/sdb1, it will mount the stick as a user, give that user full access and let it umount it.

Re: mount USB flash problem

Seens like the partition table is wrong.

Try to conect it to a windows machine, copy the files (if it works), fdisk the drive, copy them back.
